Upgrade WordPress Plugins Automatically

One of the challenges of keeping a WordPress blog running smoothly is making sure all installed plugins are updated promptly when new versions become available. WordPress 2.5 makes this easier than ever by adding an Automatic Upgrade feature.
As shown in the following illustration, the a note in the Plugin Management administration panel indicates that the Bad Behavior plugin (which I rely on to keep the spambots off my blogs) has been updated.

I have two options for bringing my blog up to date:
- Download version takes me to the Bad Behavior page on the WordPress.org’s Plugin Directory so I can read about and download the update. This functionality has been around for a while — at least since WordPress 2.3 — with all plugins that support it.
Upgrade automatically takes the update process a step further. When I click this link, WordPress automatically downloads, uncompresses and installs the new version of the plugin for me. It displays its progress as it works, as shown here, and confirms that the upgrade has been successful.
I’ve been using this new feature for a few weeks now and it’s worked like a charm. It’s a heck of a lot easier than upgrading the old fashioned way.
